Will HTML5 be what promised?

By programming in HTML, Web developers tell a browser what to do when it encounters a page.
HTML is the language a computer can understand and subsequently follow the directions to display on the user’s screen correctly all the information’s sent via the Web.
HTML itself embodies the ideal that knowledge is meant to be shared. Unlike proprietary software that hides its programming code, HTML lets anyone see and learn from its workings.
But when the Internet boom was on, HTML couldn’t handle the complexity of what people and businesses
were trying to use the Web for.
The central goal of HTML5 is to give websites the chance to expand beyond pages and into programs.
The new terms in the HTML dictionary include “canvas,” which lets a website designer insert a moving graphic that can be used in games or animations.
The language will also have tags for video and audio, which should dramatically streamline the way the Web handles multimedia: it will be as easy for a Web developer to incorporate a fi lm clip or a song as it is to place text and images.
Multimedia elements will no longer require complex code and an add-on program such as Flash. This should make Web browsers faster and more efficient.
Learning to build Web pages should become easier.
HTML5 could potentially boost security, by making it harder for attackers to dupe people into downloading malicious plug-in programs.
